A slim case for the ESP32 Devkit V4 micro-USB micro controller boards I picked up on AliExpress ESP32-WROOM-32D.

The style of this case is inspired by the Raspberry Pi Pico snap-together case by @glabifrons

Designed for a 0.2mm layer height, but I've also found it prints well at 0.28mm.  

STL, STEP, and Autodesk Fusion model file included.
